Solution extraite
The employer did not have just cause; the dismissal was not justified as an immediate termination.
Motifs extraits
The employee had only recently completed training, the employer had expected a long learning period, no deliberate misconduct was proven, the time between warning and dismissal was too short to infer persistent incapacity, and the brief late arrival did not reach the required gravity.
